I too use kexec & kexec-tools, for a couple of years now.
On IA using kexec-tools 2.0.0, use a command like this to load the kernel:
kexec -l bzImage --initrd=initrd.img --command-line="kernel-cmd-args"
where
bzImage is the kernel's bzImage file
initrd.img is the initrd image file
kernel-cmd-args are the kernel's command line args
Then, boot the kernel with:
kexec -e
